Remove unnecessary server information

Question

I am using below configuration to achieve the same and is working perfectly on local machine but not working after deployment.

 

<httpProtocol>
      <customHeaders>
        <remove name="X-Powered-By" />
      </customHeaders>
    </httpProtocol>
    <rewrite>
      <!--<rules>
    <rule name="ensurewww" stopProcessing="true">
      <match url=".*" />
      <conditions>
        <add input="{CACHE_URL}" pattern="^(.+)://(?!www)(.*)" />
      </conditions>
      <action type="Redirect" url="{C:1}://www.{C:2}" redirectType="Permanent" />
    </rule>

      </rules>-->
      <outboundRules rewriteBeforeCache="true">
        <rule name="Remove Server header">
          <match serverVariable="RESPONSE_Server" pattern=".+" />
          <action type="Rewrite" value="" />
        </rule>
      </outboundRules>
    </rewrite>
